Lisp is one of the oldest computer languages still in use today. In the decades of its existence, Lisp has been a fruitful basis for language design experiments as well as the preferred implementation language for applications in diverse fields.

The structure of Lisp makes it easy to extend the language or even to implement entirely new dialects without starting from scratch. Common Lisp, with the Common Lisp Object System (CLOS), was the first object-oriented programming language to receive an ANSI standard and retains the most complete and advanced object system of any programming language, while influencing many other object-oriented programming languages that followed.

It is clear that Lisp is gaining momentum: there is a steadily growing interest in Lisp itself, with numerous user groups in existence worldwide, and in Lisp's metaprogramming notions which are being transferred to other languages, as for example in Aspect-Oriented Programming, support for Domain-Specific Languages, and so on.

This workshop will address the near-future role of Lisp-based languages in research, industry and education. We solicit papers and suggestions for breakout groups that discuss the opportunities Lisp provides to capture and enhance the possibilities in software engineering. We want to promote lively discussion between researchers proposing new approaches and practitioners reporting on their experience with the strengths and limitations of current Lisp technologies.

The workshop will have two components; there will be formally-presented talks, and for breakout groups discussing or working on particular topics. Additionally, there will be opportunities for short, informal talks and demonstrations on experience reports, underappreciated results, software under development, or other topics of interest.

Papers ******

Formal presentations in the workshop should take between 20 minutes and half an hour; additional time will be given for questions and answers. We encourage that papers be published on the website in order to provide background information in advance.
